Interesting question. I guess it all depends on the entry in question and the campaign I want to run (I'm a player at the moment). As far as the voting goes, I am going to vote based primarily on "would I like to use it? Would my players enjoy it?" and not much else.
Regarding how I am going to use it, I see two possibilities:
1) I fit it into an existing game world somehow
2) I reserve it for another game world for a future game
Whether it is possible to fit the entry into my existing game world I guess depends a lot on how exotique or far from the rest of the setting the entry is. If we are talking about Amazon descendants of space-farers who are busy building a new space craft, then I am probably going to keep them pretty darn isolated from the rest of the world and only have my PC's visit them by accident :-)
